实现收藏与取消收藏的效果
1，html
item.remark == 'collect' 返回的参数相等时 高亮显示
```
<li
v-for="(item, index) in tableData.list"
:key="index"
>
<el-icon :class="[item.remark == 'collect'? 'collectActive': isCollection.indexOf(index) > -1]"
@click.stop="collectSbs(index, item.icao, item)">
<el-icon-StarFilled />
</el-icon>
</li>
```
2，js
```
let isCollection = ref([]);
//收藏/取消
const collectSbs = async (i, icao, row) => {
// 控制收藏图标高亮
let arrIndex = isCollection.value.indexOf(i);
if (arrIndex > -1) {
isCollection.value.splice(arrIndex, 1);
} else {
isCollection.value.push(i);
}
}
```
3，css
```
.collectActive svg {
color: #f56c6c;
}
```
